  • GEOLOGIC SEARCH FRAMEWORK
    Publication number: 20240086430
    Abstract: A method can include, responsive to receipt of input characterizing a geologic environment, utilizing a trained machine learning model to identify a number of geologic environments that include corresponding data stored in at least one database; analyzing one or more of the number of geologic environments; and outputting a result based at least in part on the analyzing.

  • Optical instrument and optical element thereof
    Patent number: 6608720
    Abstract: An optical instrument is described in which a diffractive element is located at a focal or image plane of the instrument and the diffractive element is effective to produce an array of a plurality of exit pupils at a viewing position for the instrument and thereby to form an enlarged exit pupil for the instrument. The diffractive element is formed to provide a plurality greater than two of optical diffractive gratings each being disposed angularly relative to others of the plurality of optical diffractive gratings.
    Type: Grant

    Date of Patent: August 19, 2003
    Inventor: Robin John Freeman
  • Optical instrument and optical element thereof
    Patent number: 6028704
    Abstract: An optical instrument is described in which a diffractive element (25) is located at a focal or image plane (3) of the instrument and the diffractive element (25) is effective to produce an array (6) of a plurality of exit pupils at a viewing position for the instrument and thereby to form an enlarged exit pupil for the instrument.

  • High magnification optical apparatus with rotatable reflective lenticulated surface
    Patent number: 4099831
    Abstract: The invention provides an optical device for use in microscopes and screen projectors comprising a screen formed with multiple lenticular surfaces mechanically traversed at a speed above persistence of vision in the light path between an object and an observation plane, the lenticular surfaces increasing the angle of light ray pencil egress from their angle of incidence to an extent rendering the use of eyepieces unnecessary.
    Type: Grant
    Filed: July 26, 1976
    Date of Patent: July 11, 1978
    Assignee: Vision Engineering, Ltd.
